...Though moderate levels of corticosterone may promote reproduction by mobilizing energy stores (Moore and Jessop, 2003), chronically elevated corticosterone (and stress in general) inhibits reproductive development, behavior and fertility (Moore, 1983)....

...Emerson (2001) has proposed an extension of the Challenge Hypothesis (Wingfield et al., 1990), termed the Energetics-Hormone Vocalization (EHV) Model, to explain the reported relationships between calling behavior and testosterone and corticosterone levels in male anuran amphibians....
